Electronic primary thermometry -- experimental comparison of the Coulomb Blockade and Shot Noise Thermometer
Eemil Praks, Libin Wang, Yu-Cheng Chang +4
Since the redefinition of the kelvin in 2019, new methods of primary thermometry have been considered to replace the currently agreed temperature scale in the very high and low tem…
Far- and near-field photon noise limits to the detectivity of nanometer-thick thermal detectors
Olivier Merchiers, Aapo Varpula, Kirsi Tappura +2
Thermal-radiation detectors such as bolometers -- often found as thin, suspended films -- are intrinsically limited by their optical absorption properties and by their intrinsic th…
Native-oxide-passivated trilayer junctions for superconducting qubits
Pankaj Sethi, Om Prakash, Jukka-Pekka Kaikkonen +15
Superconducting qubits in today's quantum processing units are typically fabricated with angle-evaporated aluminum--aluminum-oxide--aluminum Josephson junctions. However, there is…
Infrared Bolometers Based on 40-nm-Thick Nano-Thermoelectric Silicon Membranes
Anton Murros, Kuura Sovanto, Jonna Tiira +3
State-of the-art infrared photodetectors operating in the mid- and long-wavelength infrared (MWIR and LWIR) are largely dominated by cryogenically cooled quantum sensors when the t…
Efficient electronic cooling above 2 K by niobium-based superconducting tunnel junctions
J. Hätinen, A. Ronzani, R. P. Loreto +15
Replacing the bulky cryoliquid-based cooling stages of cryoenabled instruments by chip-scale refrigeration is envisioned to disruptively reduce the system size similar to microproc…
Wafer-scale CMOS-compatible graphene Josephson field-effect transistors
Andrey A. Generalov, Klaara L. Viisanen, Jorden Senior +5
Electrostatically tunable Josephson field-effect transistors (JoFETs) are one of the most desired building blocks of quantum electronics. JoFET applications range from parametric a…
Terahertz detection with graphene FETs: photothermoelectric and resistive self-mixing contributions to the detector response
Florian Ludwig, Andrey Generalov, Jakob Holstein +4
Field-effect transistors coupled to integrated antennas (TeraFETs) are photodetectors being actively developed for the THz frequency range ( 100 GHz - 10 THz). Among them, Gr…
Qubit-compatible substrates with superconducting through-silicon vias
K. Grigoras, N. Yurttagül, J. -P. Kaikkonen +21
We fabricate and characterize superconducting through-silicon vias and electrodes suitable for superconducting quantum processors. We measure internal quality factors of a million…
